Google Ads Enhanced Conversions: What They Are & How to Set Them Up

Google Ads enhanced conversions improve conversion tracking by using first-party customer data, such as email addresses and phone numbers, to help connect conversions to previous ad interactions.

This information is securely hashed using SHA-256 before being sent to Google for matching.

The benefit? More accurate conversion measurement and potentially better data for Google's automated bidding strategies.

How Do Enhanced Conversions Work?

Here's a simple example:

1. Someone clicks your Google Ad.
2. They visit your website and submit a contact form.
3. Their email address or other eligible customer information is securely hashed.
4. Google attempts to match that information to a previous ad interaction.
5. Eligible conversions that might otherwise have been missed can be attributed to your ads.

Enhanced conversions supplement your existing conversion tracking rather than replace it.

Why Are Enhanced Conversions Important?

Enhanced conversions offer three primary benefits:

• More accurate tracking: Help measure conversions that traditional tracking might miss.
• Better campaign optimization: Provide additional conversion signals for Google's Smart Bidding.
• Improved reporting: Give advertisers a more complete picture of campaign performance.

Better tracking doesn't necessarily mean more conversions occurred. It means Google may be able to measure more of the conversions you're already generating.

Enhanced Conversions for Web vs. Leads

Google supports two primary use cases:

Enhanced Conversions for Web

Improve measurement of website actions such as purchases, form submissions, and appointment requests.

Enhanced Conversions for Leads

Help connect offline outcomes, such as qualified leads and closed sales, to previous Google Ads interactions using customer information.

For service businesses, enhanced conversions for leads can be especially valuable because a form submission doesn't always result in a paying customer.

How to Set Up Enhanced Conversions Using Google Tag Manager

1. Open Google Ads: Navigate to Goals → Conversions and review your conversion settings.
2. Enable enhanced conversions: Choose the appropriate implementation method and accept any required customer data terms.
3. Open Google Tag Manager: Locate your existing Google Ads conversion tracking tag.
4. Configure customer data: Set up user-provided data using supported variables, CSS selectors, or your website's data layer.
5. Test your setup: Use GTM Preview and Google Tag Assistant to verify that the conversion fires and eligible customer information is available.
6. Monitor results: Review enhanced conversion diagnostics in Google Ads after publishing.

Make sure your implementation complies with Google's customer data policies and applicable privacy and consent requirements.
